Description

Technical Field

[0001] The present invention relates to the technical field of geotechnical engineering construction equipment, and particularly to an injection device for geotechnical engineering.

Background Art

[0002] Injection construction is a core construction method in geotechnical engineering for ground reinforcement, crack sealing, and slope disease treatment. By pressurizing and injecting the prepared injection slurry into the voids and cracks of the ground or rock mass, the compactness, strength, and water impermeability of the ground or rock mass are improved, and it is widely applied to geotechnical engineering construction such as foundation pile construction, roadbed reinforcement, and tunnel water shielding. The injection device is the core equipment of injection construction, and its operation convenience, slurry delivery stability, and adaptability to construction directly affect the efficiency and construction quality of injection construction.

[0003] At present, many general-purpose injection devices used in geotechnical engineering have a fixed or simple mobile structure, and many compatibility and operation problems have emerged in the actual construction process, and they cannot meet the usage needs of complex geotechnical construction sites. First, many storage tanks of general-purpose injection devices are designed with a fixed height, and the discharge height of the discharge pipe cannot be flexibly adjusted according to the site height requirements of injection construction and the position of the injection hole. Second, vibration occurs during the injection process, and the injection device is prone to displacement. However, the positioning of existing injection devices mostly depends on manual adjustment, with extremely low positioning efficiency, and due to the large weight of the device, a great deal of force is required during positioning. Therefore, in order to solve these problems, the inventors of the present invention propose an injection device for geotechnical engineering.

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below, accompanied by drawings of the embodiments. It goes without saying that the embodiments described below are not all embodiments of the present invention, but rather only a selection of them. It also goes without saying that any other embodiments obtained by a general expert in the art without creative ingenuity based on the embodiments of the present invention are included within the scope of the claims of the present invention. [Examples]

[0016] Hereinafter, embodiments of the present invention will be described in detail with reference to Figures 1 to 4. The geotechnical injection device according to the present invention comprises the following components: a bottom plate (1), a storage tank (2), a self-locking caster (3), a discharge pipe (4), a vertical column (5), a sliding groove (6), a slider (7), a movable rod (8), a transmission plate (9), a support plate (10), a tension spring (11), a oscillating plate (12), a grip rod (13), a transmission rod (14), an arc-shaped transmission block (15), a power box (16), a control device (17), a first motor (18), a feed screw (19), a second motor (20), a screw rod (21), a connecting block (22), and an electric push rod (23).

[0017] Self-locking casters (3) provided at the four corners of the lower end surface of the base plate (1) enable the movement and basic positioning of the device, push the device to the geotechnical injection construction site, adjust the swing angle of the device according to the position of the injection hole, and then fasten the locking structure of the self-locking casters (3) to complete the basic positioning of the device and prevent random slippage of the device.

[0018] The movable rod (8) slidably connected to the outside of the vertical column (5) on the bottom plate (1), and the transmission plates (9) and support plates (10) at both ends thereof are the core components for preventing vibration and positioning of the device. When the electric push rod (23) is activated by the control device (17), the new shaft rod of the electric push rod (23) extends outward, swings the transmission rod (14) away from the vertical column (5) through the connecting block (22), the transmission rod (14) rotates the swing plate (12) around the hinge point, the arc-shaped transmission block (15) at the lower end of the swing plate (12) swings in conjunction, and presses the transmission plate (9) downward. The transmission plate (9) receives the pressure and slides the movable rod (8) downward along the bottom plate (1) until the lower end surface of the support plate (10) is in close contact with the ground. At this time, the tension spring (11) is stretched, and the support force and frictional force between the support plate (10) and the ground are used to offset the vibration generated in the subsequent injection process, prevent the displacement of the device fundamentally, and perform stable positioning of the device.

[0019] The vertical columns (5) on both sides of the storage tank (2) on the upper end surface of the bottom plate (1), the slider (7) in the slide groove (6) and the first drive mechanism realize the lifting adjustment of the storage tank (2). According to the actual height of the injection hole and the height requirements of the construction site, the control device (17) activates the second motor (20). When it is necessary to raise the height of the storage tank (2), the control device (17) controls the forward rotation of the second motor (20), rotates the screw rod (21) in conjunction, slides the slider (7) upward along the slide groove (6), the slider (7) slides the storage tank (2) upward in conjunction, and the discharge pipe (4) rises synchronously with the storage tank (2) until the discharge port of the discharge pipe (4) coincides with the position height of the injection hole. When it is necessary to lower the height of the storage tank (2), the control device (17) controls the reverse rotation of the second motor (20), rotates the screw rod (2) in conjunction, slides the slider (7) downward along the slide groove (6), and further slides the storage tank (2) and the discharge pipe (4) downward in conjunction to realize precise adjustment of the discharge height, without the need for additional support tools, and meet the height requirements of different construction sites.

[0020] The discharge mechanism in the storage tank (2) realizes stable feeding of the slurry. When the prepared injection slurry is put into the storage tank (2) and the first motor (18) is started by the control device (17), the first motor (18) rotates the feed screw (19) at a high speed in conjunction, and uses the spiral thrust of the feed screw (19) to uniformly feed the slurry in the storage tank (2) downward. The slurry is pressure-injected from the discharge port of the discharge pipe (4) into the injection hole for geotechnical engineering to complete the injection construction. During the construction process, the control device (17) can adjust the rotation speed of the first motor (18), and further adjust the rotation speed of the feed screw (19) to realize flexible control of the slurry feeding flow rate and meet the slurry usage needs of different injection constructions.

[0021] Referring to FIG. 1, this embodiment optimizes the structure based on Embodiment 1, and the tension spring (11) is fitted outside the movable rod (8). With this design, the movable rod (8) plays a good guiding role in the expansion and contraction direction of the tension spring (11), avoiding displacement and skew of the tension spring (11) during use, and improving the use stability and service life of the tension spring (11).

Those skilled in the art can make various modifications and corrections to the above embodiments without departing from the technical idea of the present invention, and all such modifications and corrections shall fall within the protection scope of the present invention.
